Abstract
A combiner includes N coaxial cables each configured to connect to a respective output of N radio frequency power amplifiers, where N is an integer greater than one. Each of the N coaxial cables is configured to receive an amplified radio frequency signal from a respective one of the N radio frequency power amplifiers. A board includes capacitances and is configured to connect to each of the N coaxial cables and combine the radio frequency signals. The N coaxial cables and the capacitances provide N inductance and capacitance combinations. A connector is configured to connect an output of the board to a load.
Claims20
A combiner comprising:
- N coaxial cables each configured to connect to a respective output of N radio frequency power amplifiers, where N is an integer greater than one, and wherein each of the N coaxial cables is configured to receive an amplified radio frequency signal from a respective one of the N radio frequency power amplifiers;
- a board comprising a plurality of capacitances and configured to connect to each of the N coaxial cables and combine the amplified radio frequency signals, wherein the N coaxial cables and the plurality of capacitances provide N inductance and capacitance combinations;
- and
- a connector configured to connect an output of the board to a load.
A combiner comprising:
- a first coaxial cable configured to connect to a first output of a first radio frequency power amplifier, wherein the first coaxial cable comprises a first non-shielded section with a first inductance;
- a second coaxial cable configured to connect to a second output of a second radio frequency power amplifier, wherein the second coaxial cable comprises a second non-shielded section with a second inductance;
- and
- a board comprising
- a first capacitance connected to the first non-shielded section to provide a first inductance and capacitance combination, and
- a second capacitance connected to the second non-shielded section to provide a second inductance and capacitance combination, wherein the second inductance and capacitance combination is equal to the first inductance and capacitance combination.
